A natural gas crater in Turkmenistan has been burning since 1971, ever since an oil drilling rig collapsed into an underground cavern. Soviet engineers thought there could be substantial oil reserves there, but found methane gas instead. Instead of allowing the seeping gas to affect nearby towns near the village of Derweze (Darvaza), they ignited the gas, expecting it to burn off in a couple of weeks. Instead, it’s been burning ever since, creating a tourist attraction that brings thousands to the desolate site every year.
Locals also call the Darvaza Crater "The Gate to Hell" and "The Crater of Fire," referring to the ever-present orange flames at the bottom that continue to simmer. Tourists enjoy camping near the crater, which is estimated to be the size of an American football field.
